adaptive echo canceller的用法和样例：
- In an adaptive echo canceller,the detection algorithm able to distinguish echo pass change(EPC) from double-talk(DT) is vital to ensure that adaptive filter tap coefficients are updated in case of EPC and frozen during the DT period.
- This paper introduces the design and implementation of 2/4 lines speech interface and echo canceller. This 2/4 lines speech interface includes A/D,D/A conversion,ADPCM coding and decoding,and adaptive echo canceller etc.
- Simulation results indicate that the DC-NLMS algorithm is optimal in adaptive echo cancellation as compared with NLMS, APA, and a previously developed algorithm in the literature.
